Transport Layer
===============

The transport layer (L1) provides the physical communication interface with the TROPIC01 chip.
PyTropicSquare supports multiple transport options to accommodate different platforms and use cases.

Available Transports

   :nosignatures:

   tropicsquare.transports.spi.SpiTransport
   tropicsquare.transports.spidev.SpiDevTransport
   tropicsquare.transports.ftdi_mpsse.FtdiMpsseTransport
   tropicsquare.transports.uart.UartTransport
   tropicsquare.transports.network.NetworkSpiTransport
   tropicsquare.transports.tcp.TcpTransport

Transport Selection Guide
--------------------------

* **SPI Transport** - Direct hardware connection via SPI bus (MicroPython ESP32)
* **SPIDev Transport** - Linux spidev interface with manual GPIO CS (Raspberry Pi / Linux)
* **FTDI MPSSE Transport** - USB-to-SPI bridge via FTDI MPSSE (CPython)
* **UART Transport** - Serial communication via UART (CPython, MicroPython Unix only - NOT ESP32)
* **Network-SPI Transport** - SPI over network for remote chips (MicroPython ESP32)
* **TCP Transport** - TCP connection to Tropic01 model server (development/testing)
